Application filed September 26,1905. Serial No. 280.148.

To dal]l 10h/0111, it nto/,y concern,.-

Be it known that I, ONWARD BATES, a citizen of the United States, residing at Chicago, Cook county, Illinois. have invented certain new and useful Improvements in Piles, of which the following is a specification.

My invention relates to the construction or formation of pil# s; and in general terms the object thereof is to roduce a pile composed or built up of woo en members or sections (preferably commercial sizes of timbers) secured together and treated with cement, if desired, and to provide a novel means for facilitating the sinking or the with drawing of such pile and forming suoli ce mcnted pile.

In the present instance my improved pile consists of two or more pieces of commercial timber bolted together and provided at their junction and longitudinal of the pile with a passage for the jetting of fluid, (water, steam,

or air,) which is arranged to be discharged at the foot or point of the pile or along the sides of such pile, or both at the foot and along the sides thereof, to aid in sinking the pile in sand, earth, clay, or other soils, and to aid in removin the pile when desired after it has been anni in such materials.

My invention also contemplates the employment of Portland or natural cement or o*rout which is forced through the longitudinal ettiiig-passage in the pile and through vents or jet openings at the foot of the pile and along its sides into the surrounding i iLiterial for the purpose of solidifying such maf terial and forming a casing therefor.

The various features of advantage and utility of my improved pile will be apparent from the descrip tion hereinafter given.

In the drawings, Figure 1 is an elevation of a pile constructed according to my invention. Fig. 2 is a central vertical elevation of such pile. Fig. 3 is a transverse section'thereof; Fig. 4, a transverse section of a constructional ile modified as respects the formation ol' the ongitudinal jetting-passage, and Fig. 5 a modification of the pile in which the same is composed of two timbers.

Referring to the embodiment of my invention as disclosed in Figs. 1, 2, and 3 ol' the drawings, the pile, which may be made of any desired length, is formed of four similar wooden timbers or sections A, which in the present instance are of e ual cross-sectional area, the same being para lelograms in crosssection. These timbers or sections are arranged and secured to ether in suitable manner, as by means of tie series of bolts a, to provide around the central longitudinal axis of the pile a longitudinal jettin -passage A', which according to the particu ar construction being described may extend the full length of the pile. Thus the jetting-passage is formed by merely assembling in roper manner the four rectangular timbers without any cutting thereof. Inasmuch as a driving caIp or ring is fitted to the upper end of the pi e, it becomes necessary to lead the jettirigpassage laterally to one side of such pile at a point toward the upper end thereof. In the present instance I employ for this purpose an elbow B, whose lower end is received within the jettingassage and whose upper end extends latera ly throu li one of the timbers A to form the side opening. This elbow is provided at its outer end with screw-threads for the insertion of a host --nip le or the like to form a hose connection for t e delivery of the jetting Huid (water, steam, or air) to the central jetting-passage in the pile. Although the jettin -passa e, which is merely formed by the wa is of t e timbers themselves, will be found sufficient, it is obvious that a metal pipe might be inserted in such opening to form the etting-passage.

As hereinbefore stated, the pile may be of any len th desired; but in order to use commerciallengths of timber each section if required to be' longer than such commercial length may be built u of shorter timbers spliced together, the p an of pile with the four timbers roviding in suoli case for the use of short timbers lapping each other with only one-fourth of the cross-section of the pile cut into at any one place in its length and readily ermitting piles to be built up of any length esired.

The lower end of the pile is provided with a shoe C, of metal or other suitable material, such pile being recessed at such lower end so as to be received by the square iange c of the shoe and to preferablyv present a flush outer surface in connection therewith, as indicated in Figs. 1 and 2. This shoe may be securely fastened to the timbers with spikes or bolts a or the like to prevent any ossibility of displacement from the foot o the pile by the pressure of the jettin fluid. As indicated in Figs. 2 and 3, the s ioe is provided with a socket or chamber C', which communicates IIO with the lower end of the jetting-passage A and from which radiate a series of jet-openings c', through which the fluid is jetted to aid in the sinking of the pile.

My invention also contemplates the employ ment of jets along the length of the ile through openings extending from the j ettmgpassage A. By preference I provide lateral jetting-passages A2, conveniently formed. in one or the other or in both of the timbers at each joint or seam in the pile, although, as will be obvious, the seams themselves may be so opcnin the ordinary formation of the pile as to permit of suilicient passage of the Jetting fluid for the purposes desired, so that I do not intend to limit myself in this connection to the employment of the regularlyformed jettingassafres A2 nor to jettingpassages forme at t 1e seams, inasmuch as any passage for conducting the jettingfiuid from the longitudinal passage A to the exterior of the pile along its length is entirely Within the scope and meaning of my invention and claims.

In the form of pile illustrated in Figs. 1, 2, and 3 no shaping or cutting of the commercial timbers A is required for forming the jetting-passage A but as will be obvious from an inspection of Fig. 4 the pile may be com osed of timbers of other shapes, such as the ibur timbers D, assembled together and secured by the series of bolts d, so as to form the rectangular pile. The longitudinal jettingassage D in this instance is formed by mere y trimming or cutting off the inner corners of the timbers D before they are assembled and secured together in the manner explained.

Instead of being composed of four sections or members the pile may be composed of a less number, such as the two sections or timbers F, which are each grooved on their ad-' jacent sides to form the ongitudinal jettingpassage f, as illustrated in Fig. 5.

As shown in Fig. 2, the shoe C is provided with a series of jet-openings c, which are evenly distributed and balanced so as to discharge equally on all sides of the lon itudina axis of the pile, and thereby ma e it possible to drive the ile with more precision as to location an more nearly vertical than with the ordinary jetting process. Moreover, with the holes or jet-openings arranged on the sloping sides of the shoe there is less liability of their becoming clogged with earth, clay, Wood., or other substances than in the case of a single hole at the point of the shoe, for in the first place there is less possibility of the entrance of such substances into the openings, and in the second place it is not likely that all of the plurality of holes would become clogged or closed.

If desired, rovision may be made for drawing or pul ing the pile in a certain direction during the process of sinking it by dischargmg all or a major portincf-tlie ictfmg fiuid on one side of the will be the side toward w lich it is desired to draw or ull the pile laterally. This result may be brought about in several difl'erent Ways. For instance, the holes or jet-openings c in the shoe may be formed on one side only thereof, so as to give a jet discharge on that side alone, or the form of shoe illustrated in the drawings may be utilized by plugging up the holes on one or more sides, so as to leave open the jet-passages on that side only toward which 1t is desired to draw the pile laterally. Moreover, the result may be obtained by making the jet-passages on one side more numerous or of greater carrying ca acity than the jet-openings on the other s1 es.

When piles are sunk throu h sand, for instance, it is sometimes desirale to force cement into the sand in order that it may form aleoncrete around the piles to incase and protect them and to hold them in place, and to this end the lateral. jetting-.passages in th(x sides of the piles, as well as the longitudinal passage,is taken advantage oas a' means for discharging the cement in the form of thin gront into the surroundin sand, it beingiunderstood that the pile is st sunk into the sand in the manner hereinbefore explained and that the grout is subsequently forced into the 'etting-passages in the manner just ex lained.

y the use of my invention I am enabled to build up a wooden pile of any suitable length by sim ly using commercial lengths and forms o timbers and to provide in a simple manner means for jetting along the length of the pile and also at the bottom or foot thereof, with the result that the sinking of the pile is facilitated by the jetting operation, and, moreover, the withdrawal of pile after being sunk is facilitated b again putting the jetting system of the pilbe in operation, unless, of course, the cement process above described has been employed, in which event the jetting roeess cannot be taken advantage of in a wit drawin operation of the pile.

Although I have herein shown and described a square pile, yet it will be understood that the same may be so built up as to be a parallelogram in cross section by the employment of timbers such as those illustrated in Fig. 3, but relatively disposed or arranged as in Fig. 4, the dimensions and cross-section of the Vpile depending upon the dimensions of the timbers employed.
